Great Wroggi are deadly pack hunters that prey on Aptonoth, Bullfango, Bulldrome, Rhenoplos, and Slagtoth. However these creatures can be preyed upon themselves by larger predators consisting of Lagiacrus, Brachydios, Brute Tigrex, Plesioth, Rathalos, Rathian, Gobul, Stygian Zinogre, Royal Ludroth, and Deviljho. But if in large numbers these raptors can harass larger predators out of their territories by utilizing strength in numbers and by spitting their deadly toxic fumes.
Great Wroggi are not strong by themselves, so they form packs much like Great Jaggi and Great Baggi. This survival strategy proves useful when facing larger monsters and hunting prey. On their neck is poison sac used to produce toxins that they use to kill prey. This toxin is sprayed at prey in a mist form, poisoning prey from a distance. Venom is also contained in their fangs. To warn predators that they are poisonous, Great Wroggi have an orange colored-hide as a warning to potential predators. To indicate their leadership, Great Wroggi use their beaks.
Great Wroggi are territorial by nature, and will defend their territory and nests with aggression. They will send their packs to attack foes and hunters alike. When reaching a certain age, male Wroggi will leave their packs in order to search for and lead a pack of their own.
